Dietary sources of energy and nutrients in the contemporary diet of Inuit adults: results from the 2007–08 Inuit Health Survey
AbstractObjectiveTo characterize the major components of the contemporary Inuit diet and identify the primary sources of energy and essential nutrients.DesignDietary data were derived from the 24 h recall collected by the Inuit Health Survey (IHS) from 2007 to 2008. The population proportion method was used to determine the percentage contribution of each group. Unique food items/preparations (ninety-three country foods and 1591 market foods) were classified into eight country food groups and forty-one market food groups. Nutrient composition of each food item was obtained from the Canadian Nutrient File.SettingThirty-six communities across three Inuit regions of northern Canada.SubjectsA representative sample (n2095) of non-pregnant Inuit adults (≥18 years), selected through stratified random sampling.ResultsDespite their modest contribution to total energy intake (6·4–19·6 %, by region) country foods represented a major source of protein (23–52 %), Fe (28–54 %), niacin (24–52 %) and vitamins D (up to 73 %), B6(18–55 %) and B12(50–82 %). By contrast, the three most popular energy-yielding market foods (i.e. sweetened beverages, added sugar and bread) collectively contributed approximately 20 % of total energy, while contributing minimally to most micronutrients. A notable exception was the contribution of these foods to Ca (13–21 %) and vitamins E (17–35 %) and C (as much as 50 %). Solid fruits were consumed by less than 25 % of participants while vegetables were reported by 38–59 % of respondents.ConclusionsCountry foods remain a critical dimension of the contemporary Inuit diet.
